Conversion during Minimally Invasive Left Pancreatectomy: A Nationwide Study of Causes and Consequences.

Objectives: To identify risk factors for conversion, develop a predictive Conversion Risk Score (CRS), and assess the association between conversion and severe postoperative complications.

Background: Conversion occurs in 15-30% of minimally invasive left pancreatectomies (MILP). Risk factors and potential negative impacts on postoperative outcomes are poorly described.

Laparoscopic pancreatic enucleation: how far should we go for parenchyma preservation? A study by the French National Association of Surgery.

Background: Pancreatic enucleation is indicated for selected patients and tumours with very low oncological risk to preserve a maximum of healthy pancreatic parenchyma. Minimally invasive pancreatic enucleation (MIPE) is increasingly performed. This study aims to assess the impact of tumor location and center experience on textbook outcomes (TBO) in patients undergoing MIPE.

Pancreatoduodenectomy after Ivor-Lewis Santi oesophagectomy with gastric tube reconstruction. An European multicentre experience.

Background: Pancreaticoduodenectomy (PD) is the standard surgery to treat tumors and other conditions affecting the head of the pancreas. PD involves the division of the gastroduodenal artery (GDA) and its branches, to allow for complete dissection of lymph nodes. However, PD in patients with prior esophageal resection presents challenges due to altered anatomy and risks compromising gastric tube vascularization.

Graduated Autonomy of Laparoscopic Liver Resection Based on Liver Resection Complexity: a Western and Eastern Bi-Institution Study for Learning Curve.

Background: Laparoscopic liver resection (LLR) requires a high degree of expertise in both hepatobiliary and minimally invasive surgery. Our group previously reportwed a 3-level LLR complexity classification based on intrapostoperative outcomes: grade I (low), grade II (intermediate), and grade III (high). We evaluated the learning curve effect in each complexity grade to assess the experience needed for a surgeon to safely progress through the grades.

Debulking hepatectomy for colorectal liver metastasis: Analysis of risk factors for progression free survival.

Background: The study explores the role of liver debulking surgery in cases of unresectable colorectal liver metastases (CRLM), challenging the traditional notion that surgery is not a valid option in such scenarios.

Materials And Methods: Patients with advanced but resectable disease who underwent surgery with a curative intent (Group I) and those with advanced incompletely resectable disease who underwent a "debulking" hepatectomy (Group II) were compared.

Results: There was no difference in the intra-operative and post-operative results between the two groups.

Design and preliminary validation of a high-fidelity vascular simulator for robot-assisted manipulation.

The number of robot-assisted minimally invasive surgeries is increasing annually, together with the need for dedicated and effective training. Surgeons need to learn how to address the novel control modalities of surgical instruments and the loss of haptic feedback, which is a common feature of most surgical robots. High-fidelity physical simulation has proved to be a valid training tool, and it might help in fulfilling these learning needs.

Oncological Outcome After Laparoscopic 'No-touch' RAMPS 'Touch' Left Pancreatectomy for Pancreatic Adenocarcinoma.

Background/aim: The validity of laparoscopic distal pancreatectomy in left-sided pancreatic adenocarcinoma (PDAC) is still unclear. However, a meticulous surgical dissection through a "no-touch" technique might allow a radical oncological resection with minimal risk of tumor dissemination and seeding. This study aimed to evaluate the oncological outcomes of the laparoscopic "no touch" technique versus the "touch" technique.

Towards AI-driven longevity research: An overview.

While in the past technology has mostly been utilized to store information about the structural configuration of proteins and molecules for research and medical purposes, Artificial Intelligence is nowadays able to learn from the existing data how to predict and model properties and interactions, revealing important knowledge about complex biological processes, such as aging. Modern technologies, moreover, can rely on a broader set of information, including those derived from the next-generation sequencing (e.g.

Pure abdominal laparoscopic approach versus thoraco-abdominal laparoscopic approach: What is the best technique for liver resection in segment 7 and segment 8? An answer from the Institut Mutualiste Montsouris experience with short- and long-term outcome evaluation.

Background: Lesions in segments 7 and 8 are a challenge during standard laparoscopic liver resection. The addition of transthoracic trocars could be useful in the standard abdominal approach for laparoscopic liver resection. We report our experience with a thoraco-abdominal laparoscopic combined approach for liver resection with the aim of comparing short- and long-term outcomes.

R1 Vascular or Parenchymal Margins: What Is the Impact after Resection of Intrahepatic Cholangiocarcinoma?

: to date, long-term outcomes of R1 vascular (R1vasc) and R1 parenchymal (R1par) resections in the setting of intrahepatic cholangiocarcinoma (iCCA) have been examined in only one study which did not find significant difference. : we analyzed consecutive patients who underwent iCCA resection between 2000 and 2019 in two tertiary French medical centers. We report overall survival (OS) and disease-free-survival (DFS).

Conditional cumulative incidence of postoperative complications stratified by complexity classification for laparoscopic liver resection: Optimization of in-hospital observation.

Background: The optimal in-hospital observation periods associated with minimal risks of complications and unplanned readmission after laparoscopic liver resection are unknown. The purpose of this study was to assess changes in the risks of postoperative complications over time.

Methods: Surgical complexity of laparoscopic liver resection was stratified into grades I (low complexity), II (intermediate), and III (high) using our 3-level complexity classification.

Number of hepatocellular carcinoma nodules in patients listed for liver transplantation within alpha-fetoprotein score: a new prognostic risk factor.

In France, the listing for liver transplantation (LT) for hepatocellular carcinoma (HCC) requires an AFP score ≤2. This study evaluates whether the number of nodules assessed immediately before LT has a prognostic value among patients already listed within AFP score. Among 143 recipients transplanted with an AFP score ≤2 between 2013 and 2017 in our center, the number of nodules was considered at listing on the waiting list and at last imaging before LT.

Downstaging with Radioembolization or Chemotherapy for Initially Unresectable Intrahepatic Cholangiocarcinoma.

Objective: The aim of this retrospective study was to compare the outcomes of patients resected for intrahepatic cholangiocarcinoma (ICC) with upfront surgery or after downstaging treatment.

Methods: All consecutive patients with ICC between January 1997 and November 2017 were included in a single-center database and retrospectively reviewed. Patients were divided into two groups: upfront resection or resection after downstaging using either chemotherapy alone or selective internal radiation therapy (SIRT) combined with chemotherapy.
